Abstract: Objective  To evaluate the status of self-efficacy and its influence factors in pulmonary TB cases, then explore an effective approach to improve their self-efficacy levels.  Methods  A total of 182 patients with pulmonary TB were sampled by random number table method. General social-demographic questionnaire and self-efficacy questionnaire were used to investigate patients’ general information and self-efficacy in this study. One hundred and eighty-two pieces of questionnaires were issued and returned with the valid rate of 100.0%. Self-efficacy of pulmonary TB is divided into high, medium and low three levels. ≥ 34 is considered high level, and 25～33 as medium level, ≤ 24 as low level.  Results  The total score of self-efficacy in 182 patients with pulmonary TB was (26.45±4.99). 64.8% (118/182) of patients had a medium level of self-efficacy, Only 17.6%(32/182) of patients were in high level. Male scored (24.35±4.84), the female scored (26.74±5.19) (t=37.654, P<0.01); Those who had a personal monthly income of less than 2000 Yuan scored  (27.15±3.56), those between 2000 to 5000 scored （27.46±5.46）, and ＞5000 scored （25.32±4.54）(F=3.884, P<0.05); Patients who had a good family and social support scored (27.14±4.92), and （25.68±5.01）for those with low support（t=12.728，P＜0.01）. Patients with good psychological condition scored (26.92±5.00) and （26.53±5.07）for bad condition（t=6.284，P＜0.01). In terms of education level, patients with college level scored （27.48±4.68）, high school scored (26.32±4.91), junior high school scored (27.64±5.53) and primary school score (24.70±4.24) (F=2.837, P<0.05); Patients with positive attitude towards disease scored （26.86±4.95）, ‘does no matter’attitude scored （24.53±4.49）（t=31.042，P＜0.01）.  Conclusion  The self-efficacy in patient with pulmonary TB was affected by many factors. Therefore, we should focus on main influencing factors to take appropriate measures in order to improve self-efficacy of pulmonary TB.
